T 0 all whom it may concern Be it known that I, .Ancnnn CORNELL, sugarplanter, sub ect of the King of Great Britain and Ireland,residing atEmoyeni, Zululand, have invented new and useful Improvements in Meansfor Raising and Low ering Agricultural and other Machines, of which thefollowing is a specification.

This invention comprises improvements in means for raising and loweringagricultural and other machines, and has for its object to provide meansfor utilizing the tractive effort of the team or other meansemployed, toraise a machine from its working position on to suitable running wheels,in order to enable it to be turned around ortransported from place toplace. A further object is to enable the machine to bereadily-loweredwhen it is desired to resume working.

According to this invention the machine,

that such wheel may readily turn about its.

vertical pivoted axis to allow the machine to be readily turned orsteered when supported thereon. The tractive effort is coni-.

municated to the lever byv a'chain or the like and the lever is alsoconnected by a chain with winding means fitted with a catch or lockingdevice. When the machine is working the chain wound on the winding meanscannot unwind because such means are locked and consequently althoughthe two tive effort is on the lever the latter. remains in the positionin which 1ts runnlng wheel is 01f the ground. Immediately uponreleasing, the locking device, the tractive effort pulls over the leverand its running wheel is forcedon tothe ground and raises the machineout of the working position.

A suitable construction is shown by way.

of example in the accompanying drawing 1n wh1ch:

Figure 1 is a side elevation of a disk cultivator and Fig. 2 is a planpartly in horizontal section of the framing showing the leverarrangement and the running wheels thereon.

The cultivator comprises a framing 1 rear known type. .On'the axle ofthe disks 3 is pivoted the frame 4 which in effect is a double armedlever, the lower arm at its exwheels 2 and the cultivator disks?) of anytremity being fitted with the. casters or 1 swiveling runningwheelsfiThe upper end; I of the upper arm of the lever or frame .4- is connectedby a link 6 with a slider or block- 7 which is connected on the one handwith the haulage chain'8 and on the other hand with a chain. 9 which. iswound; around a Y winding drum 10 mounted on the rear part of theframing 1. Fixed on thegaxleof the winding drum isa hand wheel llwhichcan be operated by the handle 12 to turn-the.

drum 1O.v The wheel 11' also-hasratchet: or other suitableteeth on itsperiphery, and r a lever 13 pivoted on the axle 'ofthe drum isfittedwith a pawl 14 taking into the Said 1 teeth. A lever 15 pivoted to? theframing carries detents or teeth 16 which catch into the teeth ofaratchet wheelforming'one end of the drum l0, and a blade spring-17 constantly presses upon the lever 15 in the di rection for maintainingthe'teeth 16 inengagement withthe teeth of the. said drum ratchet wheel.y

,lVhile the machine is at work, the chain 9 is wound up on the drum 10and is pre vented from unwindingby'the detent 16.

The lever 4. is thus held by the chain in the 7 position seen in dottedlinesv in Fig. 1, in which positionthe running wheels or casters 5 areoff the ground so as to allow the cultivator disks 3 to operate. When itis desired to raise the/machine from its working position and tosupportit entirelyon run-v ning wheels, the lever- 15 is lifted and removes thedetents 16 from the teeth of the drum ratchet wheel. The tractive efforton the chains 8 and 9 is then. tree to unwind'the chain 9 from the drum10 and to" pull the upper arm of the lever 4 forward. Consequently therunning wheels 5 are lowered and forced into running contact with theground as seen in Fig.1. This movement of the lever is either limited bya suitable stop or stops, or the chain 9 attached to the drum 10 is ofjust sufficient length to allow the lever 4 to assume the requiredposition. After this position has been attained further tractive eflortwill" simply haul the machine along on its supporting wheels; When it isdesired to. resume working, the chain 9 must be wound on to the drum 10again; this is accomplished when the machine is light by simply turningthe hand wheel 11 by the handle 12 in the proper direction. lVhen themachine is heavy however the hand lever 13, is-worked upand down, thepawl 14 engaging the teeth on the wheel 11 at each alternate stroke ofthe lever 13 and feeding the wheel around in step by step fashion. Thedetent 16 holds the wheel 11 and drum 10 in the position. to

which they have been turned at any moment.

by the means above described.

t will be obvious that the apparatus is capable of being controlled bythe driver or controller of the machine who is able to operate thevarious devices Without leaving his seat.

1V hat I clainras my invention and desire to secure by Letters Patentis 1. In means for raising and lowering agricultural. and othermachines, a two armed lever pivoted to said machine, a running wheelmounted at the free end of the lower arm, a winding drum on saidmachine, hand operated means to rotate said drum, a haulage chainconnected between its ends with the upper arm of said lever and fixedlyconnected atone end to said drum, and releasable locking means operativeupon said drum substantially as set forth.

2. Inmeans for raising and lowering agricultural and other machines, anoscillating frame pivotally mounted on said machine, running wheels atthe lower end of said frame, chain'connections with the upper end ofsaid frame, a winding drum adapted to wind up one of said chainconnections, and a releasable holding means operative upon saiddrumsubstantially as specified,

3. In means for raising and lowering agricultural and other machines, alever pivotally mounted between its ends on said machine, a runningwheel mounted on the lower end of said lever, a chain, a drum adapted towind up said chain, a link connection between the upper end of saidlever and said chain, a toothed wheel connected with said drum, a detentadapted to engage-the teeth of said wheel, and a spring constantlypressing'said detent toward said wheel substantially as set forth.

t. In means for raising and. lowering ag-' ricultural and othermachines, a swingable two armed. lever, a running wheel on one mainframe and permanent running wheels,

the combination of a swingable double ended lever pivotally mounted on.said frame, a temporary running wheel ofthe caster variety on one end ofsaid lever, a3

haulage chain, a connectionbetween the other end of said lever and saidchain,

winding means mounted on said frame and operatively connected with saidchain, locking means operative upon said winding means, and releasingmeans operative upon said locking means substantially as setforth;

6. In' a portablemachine comprising a main frame supported in workingposition by an implement and permanent running wheels, the combinationof a swingable lever pivoted between its ends on said frame, a temporaryrunning wheel of the castervariety on one end of said lever, a haulagechain, a connection between the other end of said lever and said chain,winding means mounted on said frame and operatively connected with saidchain, driving means for said drum, locking means constantly tending toengage and hold said drum. against: an, unwinding movement, andreleasing; means for said locking means, substantlally as set forth. a

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
